[PATCH] UBIFS: remove unneeded function parameter

[Artem Bityutskiy]

From: Artem Bityutskiy <Artem.Bityutskiy@xxxxxxxxx>

Simplify 'ubifs_jnl_write_inode()' by removing the 'deletion'
parameter which is not really needed because we may test
inode->i_nlink and check whether this is a deletion or not.
